The plugin SafeBuckets, the one that makes our water still by default, I feel has become more and more useless lately, and I think its future needs a serious discussion.
I feel that SafeBuckets needs to be unplugged, and here is why:
First of all SafeBuckets is very un-vanilla as a plugin, since it's not normal to see still liquid in Vanilla Minecraft, and thus goes against the server's theme.
Secondly the still water it gives is rather useless. While it does make water elevators and some lava killing machines easier to build, it does not really add anything irreplaceable to the game: some signs surrounding flowing liquids will accomplish the same thing still water gives to us now. And while some water elevators arguably look prettier without signs in between water blocks, I would not consider water elevators pretty to begin with. Some may disagree.
But most importantly I feel that SafeBuckets's primary function as a grief-prevention plugin is so unimportant that it practically does not matter. Griefers, as far as I can tell, are not persistent enough to acquire a bucket just to knock someone's flowers or torches over. And even if they were, the loss is hardly meaningful. As for more serious griefing like murdering with lava or making derpy lava walls around, those are easily traceable nowadays.
At worst a griefer may attack someone's rails or redstone, which is actually quite severe, but that they can do with natural liquid sources even now. A much better option would be to write a plugin that makes rails and redstone waterproof.
A plugin like that at least would not encumber the staff day and night, like SafeBuckets does.
SafeBuckets also makes a few things if no impossible, at least very hard: It is impossible to dispense flowing liquids and this must be worked around with silly piston gates. Making ponds is tough because of the glitchy interaction with still and flowing water that makes some parts of the potential pond not fill up like it is supposed to. Nowadays you'd need constant mod surveillance just to make an artificial lake.
The absence of SafeBuckets would obviously be beneficial for everyday building, but it would be particularly useful for making grinders. For example in a skeleton grinder getting the water to flow immediately would make building much less dangerous much faster. In an Ender grinder the benefit of getting immediate water cover is obvious.
In summary, SafeBuckets is un-vanilla, seriously hinders everyday building, encumbers staff, and is irrelevant against griefing. If I was king, I'd replace it with another plugin like the one described above.
But, all of the above was only what I think. I may be right, I may be wrong, some may even disagree. What I want here is a serious discussion on this matter. The server's interests are largely also my interests, and that's why I'd want a thorough investigation about this matter so at the end of the day we can be sure we're making the right decision.
